In OS X, preferences can be use as a similar function to what you want in Registry. &nbsp;Have a look at this <a href="http://www.oreillynet.com/pub/a/mac/2001/08/24/cocoa.html" rel="ugc">http://www.oreillynet.com/pub/a/mac/2001/08/24/cocoa.html</a>

Hi. &nbsp;I built an app for windows..works great. &nbsp;I'm currently building app for mac on os x 10.2.X and higher platform. &nbsp;When my user pops in the cd to install app, I want it (like windows) to detect if:<br />
<br />
1.) app already exists on machine<br />
&nbsp; &nbsp; &nbsp;a.) If not, install app, online reg, throw back something to mac registry that unlocks app.<br />
&nbsp; &nbsp; &nbsp;b.) If app already exists on machine, don't install<br />
<br />
<br />
I can do all of that on windows because of registry. &nbsp;Is this doable on mac? &nbsp;If not, what is the alternative to prevent app piracy? &nbsp;How does mac prevent others from moving exe from one mac to another without some sort of system check on the app?

Kernel and system programming is the process of creating the software necessary for a computer or device to function and operate other programs. Some operating systems (such as Microsoft Windows) are proprietary, but others, such as the various Linux distributions, are open source.
